I am using tvm solver ..don't need formulas
here is what i input correct me if i am wrong ...
HERE IS MY TVM SOLVER ANSWER PLEASE CORRECT ME IF WRONG. PLEASE POINT WHERE IS THE ERROR

Using the t1-83 plus TVM solver or similar tool. create complete tables like the following to see which option is the
most effective investment. the choices are monthly payments of $200 at annual interest rate 5% for 10 years(option
A). doubling the payments (option B). doubling the interest (option C) or having the payment/compounding periods
take place twice as often (option D).
STATE WHICH OF THESE OPTIONS IS THE BEST AND WHY IT IS THE MOST EFFECTIVE.

don't have the tvm solver any one can help
thanks
Hi,
The compound interest formula:
orwhere A is the Amount, P is the Principal, r or i is rate of interest per period (e.g. per month, per quarter, per annum etc.).
1.) When i increases, and n also increases, A and P increase. When i decreases n also decreases, A and P decrease.
when i increases and n decreases, or vice versa, the change is caused dependent on the values.
2). Amount and Principal is dependent on i, as well as n.
thanks for replying...
for 1:) since n is constant i think its just Simple interest and principle
if
n = 1
=A = P(1+i)^n =
=P(1+i)^1
= P(1+i)
now we know that i = r/n
since r n=1,
i = r = interest rate
then we have A = P + P*i
i think its just Simple interest and principle and we have
now the This is a linear equation.
for 2:) TRICKY
if i is a constant, this is an exponential equation `a=b^n` where `b=P(1+i)` , `b` a constant. if (In this case, P is a parameter)
and so on for a, b
please correct me if i am wrong
thanks
hello
please i need help understanding both questions
use the compound interest formula a= p(1+i)^n to answer the following questions:
1:) what type of equation is present if n is constant equal to 1, rather than a variable?
2:) what type of equation is present if i, A, or P are constant rather than variable?
thanks
Hi,
The Answers A, C, and D are partially correct.
That is,
A) First diff. = 24, 24, 24; Second Diff. = 0 : Linear. Common difference is the same in first difference. Arithmetic Progression.
C) First diff. = 18, 34, 50, 66; second diff. 16, 16, 16 : Common difference in first difference is increasing in Arithmetic Progression : Quadratic.
D) First diff. = -7, -17, -27, -37. -47. Second diff. = 0. Common difference is the same, that is -10, in first difference. Linear.
Regarding B,
The first differences ought to be 3, 27, 243, 2187, 19683.
First difference = 24, 216, 1944, 17496. (Not 17676).
Second diff. = 9, 9, 9 :
The series is Exponential, in first difference.
Thanks much
I am glad i posted the questions i thought i was right!! ...
Thanks for correcting my answers

hi yorkmanz
Yes, that's right. Do you need more help with the rest?
Bob
thanks much.
for Question 5 any formula i can use to solve it
thanks
hi yorkmanz
Here's what I think.
For section A the temperature is going up (positive). The line is straight meaning the rate of increase is constant. Then at 20 minutes there is a sudden change to a steeper line, so the rate is still positive and constant but at a greater value. At C the temperature isn't changing so the rate of change is zero. Finally at D the temperature is going down so the rate is now negative. The curve here isn't straight so the rate is changing. Heat loss is fastest to start with and then, as the curve levels off, the rate of loss is less and less.
To get the final answer the temperature has increased by 30 degrees C in 20 minutes. The rate of change is measured by dividing the 'up' by the 'across', ie 30/20 and the units are degrees C per minute.
Note: 3) had two letters
Hope that helps,
Bob
For 3) since its going positive i t should be A AND B?
so C IS STOPS
A liquid is heated in lab using hot plate the graph temperature vs time is shown below
https://imgur.com/c6ehBn5
answer using letter A, B, C, D FROM THE ABOVE GRAPH
1) WHERE IS THE RATE OF CHANGE ZERO?
2) WHERE IS THE RATE OF CHANGE CHANGING?
3) WHERE IS THE RATE OF CHANGE POSITIVE?
4) WHERE IS THE RATE OF CHANGE GREATEST?
5) CALCULATE RATE OF CHANGE FOR SECTION A, INCLUDING UNITS?
MY ANSWER FOR
1) C
2) B
3) A
4) D
5) NOT SURE HOW TO SOLVE
PLEASE CHECK MY ANSWERS AND HELP ME
THANKS
